How to request data – for HollandPTC, Erasmus MC, LUMC and TU Delft scientists only
Before you can use our data, your data request will be reviewed, please follow the steps below. Take in consideration that, depending on the research, it will take some time to determine the dataset and receive the approvals (the second and third step).
If you would like to use HollandPTC facilities for a specific study and the data request is part of this, your research proposal will be reviewed as a whole. Please read more about the review procedure for your research proposal on how to apply to use our research facilities.
- Fill in the data request form below
- We will get in contact with you to determine what data you need.
You can use data of one or more test patients to get a better idea of the possibilities and to determine if you can perform the required analysis on the data (also concerning the type of anonymization we’ve applied).
- Your data request will be reviewed.The same review criteria apply as for a research proposal.
- If the dataset is determined, the request will be send to the data access panel for the final approval.
Review criteria of the data access panel are:
* does the data request matches the research question?
* is only data requested that is actually needed?
* is the privacy of patients protected?
- After approval by the data access panel, the Data Transfer Agreement is prepared (DTA), with the appendices:
* the R&D checklist or description of data request (as project description)
* the review form of the data access panel (as description of the data)
* the HollandPTC publication guidelines
- Once the DTA is signed by both parties, and the dataset has been prepared, the data will be transferred to you.
- The data request is finished once you indicate you received that data in good manner and are able to start you data analysis.
